Encrypt anything.
Trust nothing but math.

CryptVault seals your files and text with AES‑256‑GCM, right inside your browser. No uploads, no servers, no accounts holding your secrets — just the Web Crypto API doing what it does best.

AES-256-GCM

Authenticated encryption that detects tampering instantly — the same cipher trusted by banks and governments.

PBKDF2 · 250,000 rounds

Your password is stretched through SHA-256 a quarter-million times, turning brute-force guessing into a losing game.

Zero-Server

Every byte stays on your device. There's no backend to breach, subpoena, or leak — because there isn't one.

How it works

  1. 01

    Sign in

    Continue with your Google account to enter the vault.

  2. 02

    Choose text or a file

    Type a message or drop in any file, then set a password.

  3. 03

    Seal or unseal

    CryptVault derives a key locally and encrypts or decrypts in your browser — nothing is ever sent anywhere.

Your secrets deserve better than a server.
